The bright yellow background and the prominent "40%" discount offer.

The ad opens with the NS Zakelijk logo and the word 'Combin' partially visible. It then transitions to a full view of the text 'Combineer de NS-Business Card met het Dal abonnement.' A blue NS-Business Card is shown with various icons representing services. A red circle with '40% korting in de Daluren' is prominently displayed. The background is a bright yellow with a white curved line. The pacing is slow and deliberate, focusing on the card and the offer.
